fuel lines

[MARINES185]

I have 50lb injectors and walbro 340 pump. would increasing
my fuel line diameter to 7/16 from the tank to fuel rail be
worth it? i'm looking for more volume and less pressure or
will my fuel rail still be a restriction?

LOTS of people run mid 10s with stock fuel lines!!!

if you want more volume, get a double pumper kit that installs in the tank-

how fast is the car presently?

the car ran best of 13.28 on street tires,street chip,100 oct
and exhaust. i just rebuilt the motor and i heard lots
of guys say low 11s are max for 50s. i only want low 11s
but i don't want my injectors maxed out.

Your stock lines are fine - I ran 10.5's all day with stock lines, Reds double pumper and 72# injectors. Im looking to run mid nines with a new stage motor and Im considering still using my stocklines, have fun. Larry
